To' all whom it may'concem: v

Be it known that I, LAWRENCE P. HILL, a citizen of the United States, residing at Caratunk, in the county of Somerset, State of Maine, have invented certain new and useful Improvements in Bicycle-Boats; and I do hereby declare the following to be a full, clear, and ex` act `description of the invention, such as enable others skilled inthe art to which it appertains to make and use the same.

This invention relates to devices known as bicyle boats, which, as their name implies, are boats which arev propelled manually in a manner similar to the propulsion of a bicycle.

The invention relates more specifically to that class of bicycle boats in which the propelling mechanism is mounted' upon spaced floats and the primary object of the invention is to provide a novel form of propelling mechanism and a non-collapsible construction of lloat. In the accompanying drawings:-Figure l is a side elevation ofthe invention. Fig. 2 is a rear view there.- of. Fig.. 3 is a vertical longitudinal sectional view through the same. Figml is a detail plan view of one of the floats, a portion of the cover being removed.

Referring to the drawings, the numeral 5 designates the floats of mybicycle boat, the said floats being tapered at each end and composed'of a light metal skeleton frame including strips 6 which extend longitudinally of the floats and which are connected at their corresponding ends, as shown, at '7, and annular bracing strips `8 to which the strips 6 are secured. Eachloatlalso includes a covering 9 of rubi; 1f* or other suitable material which is stretched over` the framework o the float and inflated with air to render it buoyant. `vSecured to correspondingones of the strips 6 o the ioats adjacent the front and rearends of the same are sockets-10, 1l and 1 2 and secured at their lower ends in the sockets 10 and l1 and converging upwardly therefrom are pairs of standards 13 and.14 respectively, 'the said standards of each pair being connected by means of upper and lower cross bars l5 -and 16 and 17 and 18respe`ctively, which serve to brace their respective standards and hold the oats in spaced relation.

Mounted upon the connected upper ends of the standards 13 and 14 is a seat 19 and mounted to turnf in front of the said seat, in the cross bar 15 and a bracket 2O carried by the standards 13 is a steering shaft 21 having a handle bar 22 by means of which it may be turned. Secured at their rear ends in the sockets 12 and connected at their forward ends to the standards 14 are bars 23 and mounted upon the said bars4 are pulleys 24. Supported by means ofa bracket 25 from thecross bar 18 is a rudder blade -26 and connected at one of their ends to opposite sides of the blade are cables 27 the said cables being engaged with the pulleys 24 and connected at their opposite ends to the handle bar 22 adjacent each end thereof. `A bracket 28 is carried by' the standards 13 and mounted'in the bracket upon .a crank shaft 29 is a sproeketgear 30,*the said crank shaft 29 being provided with pedals whereby the same may be rotated as will be readily? understood. Rotatably journaledvupon the cross ba'r 17 is a sleeve 31 carrying sprocket gears 32 and 33 which are located adjacent each end of the sleeve 31 and engaged with the sprocket gears and`32 is a sprocket chain 33, thus providing means for rotating the sleeve.

Mounted tol rotate in suitable bearing brackets 321 and 35 is a propeller shaft 36 carrying a screw 'propeller 37 Awhich is tapered froin its front to'its rear end as shown, and mounted ipon a counter shaft 38 is a sprocket gear 39 with which and the gear 33 is engaged a chain 40, the said counter shaft and driven shaft being connected by means of bevel gears 41.

Having thus described the invention, vwhat is claimedzl A device of the class described comprising spaced floats,

standards extending upwardly from the floats and connected at their upper ends, a seat supported upon the upper ends of the standards, a crank shaft journaled be' neath the seat, a propeller shaft journuled beneath the crank shaft and between the oats and in parallel relation with respect thereto, gear connectionshetween the crank shaft and the propeller shaft, rods connected with the floats and extending upwardly therefrom and thence forwardly und connected with the rear standards, pulleys jourualed upon the rods a handle bar arranged in front 'of the seatfor turning movement, a rudder mounted rearwardly of the propeller, cables connected with the ends of I the handle bars and engaged `around the pulleys and connected with the rudder.

Intestimony whereof, I aiix my signature, ln presence of two witnesses.
